2-2 Initial Setup

Making Electrical Connections

Before making measurements with the TransPort, you must make

all the necessary connections to the unit. This section describes

how to connect the following:

• Power

• Transducer

• Analog Input/Output

• Infrared Interface

Make all connections to the top of the TransPort unit as shown in

Figure 2-2 below. Please note that you only need to make the

proper transducer connections. The other connections are

required for particular functions, but are not necessary for basic

operation.

Power Connections

The PT878GC is powered by either a 100-120/200-260 VAC

wall mount plug-in module, or by 5 internal C

-size NiCad high-

energy rechargeable batteries or by a pack of 3.0 Ahr NiMH

batteries. (An optional power supplement, part #703-1283, uses 6

AA alkaline batteries.) When you receive the PT878GC, the

batteries are not charged; therefore, to make remote

measurements using the batteries, follow the instructions on

page 2-5 to charge the batteries. In either case, you must connect

the power cord to the appropriate terminal as shown in Figure 2-2

above.
